ADVERTISING DEV-ICE.

To all whom it may concern:

.Be it known that I, NVILHELM Fnnnnnioii FLonssELL, a subject-of theCzar of Russia, residing at 350 George street, Sydney, in the State ofNew'South Wales, Commonwealth of Australia, have invented certain newand useful Improvements in Advertising Devices, of which the followingis a specification. I This invention relates to improvements inadvertising devices of the type in which the advertising'space ismovable or capable of variation, the necessary motion being -ob-.

tained preferably through the agency 'of clockwork, or an electricmotor.

The invention consists of a series of'parallelrotatable units whoseadjacentgfedges almost meet, thereby-forming a practically continuousadvertising gspace of any size d esiredl These unitsareoftri 'ngularsection,

and each is provided withja projecting 'arm for each of itsjigthreefacesg and with .a disk qui'distanujrecesses which a springepresseddetentas adapt;

having three.

one end of ed to engage to a'ct as-afstop.,QAdjacent-to one end of thesections is'ai'ranged an operating element equipped with projectionswhich aredesigned to engage the projections on the units, so as tion ofthe latter during the movement of vention may beclearl y comprehended, Inow refer to the drawings herewith, in which Figure 1 is a frontperspective view, and, Fig. 2 a rear perspective view with the door ofthe casing raised. Fig. 3 is a section on the line 3-3, Fig. 2. Fig. iis a section on the line 4l-l, Fig. 3. Fig. 5 is a section onsubstantially the line 5-5, Fig. 4:. Fig. 6 is a fragmental plan view ofa modified actuating gear. Fig. 7 is a-perspective' view illustrating aportion of a preferred form of a unit. i

The same numerals indicate the same or like parts.

10 is a casing having an opening ll in 'front and a door-12 at the rear.

13 are the afore-meiitioned rotating units which, as stated, aretriangular in section, the entire series of these units forming thesign. The lower trunnion it of each unit fits in a ball boa-ring 15, andthe upper trunnion 1.6 in a bearing 18. On the trunnion 16 is a disk l9having, integral therewith the arms 20. In the disk are three wuidistautrecesses 21 into which takes the pin or other 7 Specification of LettersPatent.

the rear of the series of units is arranged the actuating mechanism forvthe same, .said.

mechanism being here shown as consistin'g of the sprocket chain 24' andsprockets 25 and 26, the chain being actuated by the sprocket 26 on theshaft 28 driven by the ,worm 29 andfworm wheel 30, the' motive powerpreferably being an electric motor 31.

The units 13' forming the sign of wood, glass, metal, or othersuitablemate- ,rial, having the component parts of theisign- 5 paintedor otherwise illustrated on them.

Ifreferably, however, the three sides or panels 33 are held in groovesand are removable individually (Fig. '7), in order that ';variations ofthe sign maybe readily efi .fected by substituting fresh panels. h Inorder to Iminimize the noise of the the form illustrated in Fig. Ghasradially projecting teeth 35 on said Wheel being" engageable by theteeth- 36 of the wiper secured to the chain 24. f i i The operation ofthe invention is asfollews:'-The corresponding panel of each unit isillustrated to show apor'tion of a sign or advertisement, so that thewhole sign I the whole of the "corre- 'SPOIldlllgPtlllGlS. On actuationof the chain may be shown by by the motor, the \viper'is broughtintocontact with :tprojection on the first unit and forces the 'latterto rotate past the detent 22 one third of a revolution, thereby showinganother panel or surface, and similarly as it passes each successiveunit. The sign is then' fully displayed and remains so until the wiperagain reaches a position where it will act upon the units and cause themto show another sign. It will be evident that, by causing the chain '24to move in the opposite direction to that shown in the drawings, thesign may be operated'in a direction opposite to that shown,

It is obvious that instead of a horizontally displayed sign it may bearranged to be displayed at any angle.

' I claim 1. In an advertising device, the combination of a, series ofrotatably-mounted,..tri

lateral units arranged in juxtaposed, parallel relation; a disk securedto one end of each unit-and provided with a plurality of radialprojections and with a series of three i I; 5 i

'equidistantly-spaced, V-shaped peripheral recesses; a movable operatingelement having projecting means thereon for engagement with theprojections on said units, to rotate the latter through one-third of arevolution; and a spring-controlled detent engageable in the recesses ineach disk at the conclusion of each rotary movement, while permittingrotation of the units in either direction upon their axes. Y

2. In an advertising device comprising, in combination, a-series ofrotatably mounted, prism-shaped units arranged in juxtaposed, parallelrelation, each unit having its side faces provided with movable panels;a disk secured to one endiof each unit and provided with a plurality ofradial projections and with a series of three equidistantly-spaced,V-shaped peripheral recesses independently separate of said recessesformed by said projections, means to engage with the projections forimparting a step-by-step rotary movement to each unit in succession andto successively display each panel. thereof; a spring-pressed detentmovable longitudinally of itself into and out of engagemeiit with saidV-shaped recesses to' yieldingly lock the units in position at theconclusion of each rotary movement thereof, while permitting rotation ofthe units in oppositedi rections on their axes; and means for adjustingthe spring tension of said detent.

3. An advertising device comprising, a casing formed with a displayopening in one wall thereof and having an opposite wall in. hingedrelation therewith, a,plurality of rotatably mounted, trilateral unitsarranged to have their ed es in juxtaposed, parallel relation andadapted to close said display opening, spindles formed on the ends ofsaid units, bearings for said spindles secured to the casing anddisposed adjacent said display opening, the upper end of -said unitsbeing formed with a circular reduced portionhaving a series of threeequidistantlyspaced, V-shaped recesses therein, a disk secured to theupper end of each unit and provided with a plurality of radialprojeceach side of the units, a supporting bar secured in the casing andadapted to extend transversely of said units, a plurality of hollowmembers supported on said bar and opposite each unit, a detent for eachhollow member having slidable engagement there 'with and adapted toengage with the V- shaped recesses insaid unit for locking the same inpositlon at the concluslon of each rotary movement thereof,'whilepermitting rotation of the units in either direction upon their axes,spring means in said hollow members for yieldingly holding said detentsin engagement with said recesses, and adjustable means carried by saidhollow members for-varying the tension of said spring means upon saiddetent.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
